The Wemo Smart Light Switch allows you to control lights and ceiling fans from the wall, the Wemo App, or with your voice*. This smart light switch connects to your existing home WiFi network to provide wireless control of your lights â€“ with no subscription or hub required. Now compatible with 3-way light configurations, the Smart Light Switch can be installed almost anywhere. From porch lights to ceiling fans to recessed lighting, it can control nearly anything that a traditional light switch can and only requires one Smart Light Switch per 3-way circuit. Whether you’re unwinding on the couch, working at a coffee shop, or vacationing in the Caribbean, you’ll be able to remotely control your home lighting from anywhere.
